How to dissolve epoxy resin - the best ways

How to dissolve epoxy resin - the best ways How to dissolve epoxy at home

When carrying out repair work, adhesives or other materials often fall on surfaces in the house. It is not always possible to wash them right away - some chemical compounds are stable, they are quickly absorbed into the base. It is extremely difficult to get rid of epoxy stains - a durable and deeply absorbent product. Before you dissolve the epoxy, the risk of damage to the system should be assessed in advance - sometimes only the most gentle methods should be used.

If we talk about epoxy resin, then this is a substance with an unusual structure, and its chemical-type formula is presented in the form of short polymer chains, which will give the composition a special degree of strength.

Together with the hardener, you can use a casting compound - on its basis, self-leveling floors, figurines and decorations will be made. Another epoxy resin will be part of the adhesive of the same name.

Features of epoxy resin

Curing of any epoxy-based materials is performed only after it comes into contact with a hardener - a special solution that starts the polymerization process. If the tar stains can be hardened, it will be very, very difficult to remove. This will be due to the properties of the material - resistance to moisture, mechanical damage, scratching, thermal stability.

It will be much easier to dissolve or even remove resin-based stains before it has completely cured. In this case, it will be much easier to clean them, although traces on the surface are ways to remain forever.

Please note that all necessary precautions should be taken in advance to avoid the need to remove defects. Surfaces near the working area should be covered with cellophane or newspapers. It is worth wearing gloves on your hands - a chemical-type compound will often cause burns or allergies in contact with the skin.

Basic methods for cleaning stains

The choice of the method that is allowed to remove epoxy in the home will depend on the size of the spots, the age of the appearance, and how delicate the base material is. Sometimes it is worth removing the defect mechanically, and in other cases, an epoxy-type solvent should be used. The main principle of washing off the product will be to start the process of the reverse type, when the solidified mass begins to liquefy again. This can harm the surface, and therefore, with its value, less aggressive methods are used.

Heating the base

A large amount of heat, even excessive heat, will always be generated during the polymerization reaction of the epoxy resin.

This will be due to the peculiarities of the chemical type reaction - the combination of epoxy groups and hardeners provokes heating of the mixture. This will be the basis for the method of dissolving the adhesive composition after returning it to its original state of aggregation.The method is useful for washing away resin deposits from furniture and tiles. For the thermal treatment of the site, a building hair dryer should be used.

The technique for removing the solidified mass will be as follows:

  • Wipe the surface of the area with acetone, white spirit or other degreaser to dilute.

  • Turn on the hair dryer, heat the stain to more than +180. . + 190 degrees (usually this is the limit of thermal resistance of epoxy resin).
  • As it warms up and liquefies, the bead should be cleaned and a little acetone may be dripped inside the stain to make it easier.
  • It is better to wipe the defect with a soft cloth or a sponge for washing dishes, and if necessary, you can use a sharp knife.

  • The rest of the material should be warmed up, repeat the procedure until the object is 100% clean.
  • Typically, the entire stain removal process takes less than 5 minutes.
  • If desired, a soldering iron can be used instead of a hair dryer and can be used to heat the resin through the paper.

Please note that boiling of the mass during heating is completely undesirable. This can cause its rapid folding, and then the solubility will seriously decrease.

Cleansing them should be done in small areas, and still warming them up consistently. When cleaning wood, acetone should be used as a solvent, which will prevent cracking of the material from heating.

Freezing contaminants

How can epoxy be dissolved if the previous methods do not work? To implement the method of freezing contaminants, it will not be necessary to place the product in the freezer, and, moreover, this is far from always realistic. It is worth buying a special refrigerant in the store, which is sold in the department for repair and construction. Working with such substances is allowed only with the use of personal protective equipment.

For this reason, in parallel, you will need to buy a respirator, glasses, and gloves. Without them, there is a great risk of damage to the body by solid fragments.

The procedure for removing stains is as follows:

  • How to dissolve epoxy resin - the best ways Open windows or turn on the supply ventilation.
  • Remove children and pets from the area.
  • Shake the refrigerant can thoroughly.

  • Spray the product over the area of ​​resin that has hardened from a distance of 0.3 meters (the bottle should only be held with the neck up).
  • After the stain becomes brittle and begins to crumble, it should be quickly wiped off, scraped off with a knife or even a metal spatula. You can also break it with a hammer and collect it with a vacuum cleaner, broom.
  • If necessary, the refrigerant should be sprayed again.

  • Epoxy shards should be discarded immediately and packed in a sealed plastic bag.

Let's consider one more method.

Mechanical removal

This method is best suited if the resin cannot be washed off mechanically, and the thermal type of exposure can harm the vulnerable surface. In such a situation, you should take a sharp knife (for example, the same stationery), a razor, and a thin metal spatula. With such an object, you should carefully clean off the resin drips until you see the base material.

Cut the stain off in layers to avoid accidentally damaging the base. With a large area of ​​contamination, you will need to be patient - the process promises to be laborious.

Chemical types of solvents

Epoxy is a soluble material, but not all solutions can wash it off. A distinctive property of the resin will be chemical resistance, and therefore it will be necessary to select a really aggressive substance in order to soften the stains. On the composition, even when buying, you should read whether they fit the existing type of surface.

Most types of solvents can ruin the skin, leave stains on the stone, and can literally burn plastic. You should be especially careful with expensive pieces of furniture, as well as fabric coverings.

How to dissolve the cured epoxy so as not to damage the base? You can try using acetone, an enamel or varnish thinner. To begin with, you should drop a little product in the center of the influx, and also follow its reaction. If it starts to soften, then the epoxy can be completely washed off.

Wipe the resin areas with such products, and in parallel clean the surface mechanically. It is important to work only in a respirator, as well as to open windows and doors. It is better to carry out work altogether in the fresh air, because the fumes from such liquids are very toxic. It is impossible to immediately pour a lot of solvent onto the surface of wood or plastic, because in this case the material will most likely be damaged. How can epoxy be diluted? It dissolves perfectly in methylene chloride, but it is so dangerous and caustic (carcinogens) that it is definitely not worth risking your health.

At home, craftsmen often try to wash off the resin with similar substances:

  • How to dissolve epoxy resin - the best ways Nail polish remover.
  • Denatured alcohol.
  • Sulfuric acid.
  • Flush SP-6.
  • DMSO and DMF.

How to remove the product from skin, clothes and other coatings?

Removing the product from the skin

It also happens that epoxy glue gets on the skin of the hands or other areas, and this is especially common when working without gloves. If you do not respond in time, then there is a risk of chemical burns or contact dermatitis. Do the following:

  • Wash skin immediately with soap and water.
  • Rinse the stain area with disinfectant, if available.
  • Thoroughly wipe the spilled area with a paper towel or soft towel.

You can still remove the stain from your hand with acetone, but people with sensitive skin should not do this. You can wipe with a nail polish remover or acetone only the area where the resin gets in, but not completely the hand, as otherwise large cracks may appear on the surface of the skin. Then wash your hands with soap and rub with any nourishing cream. If the contamination has hardened and remained unnoticed, it should be soaked in any vegetable-type oil until completely detached.

Washing from clothes

After getting the composition on the fabric, the stains will begin to be absorbed very quickly, and harden no less quickly.

Aggressive techniques can destroy fibers, and for this reason, cleaning will lead to irreversible damage to things.

But small resin drips can be tried to clean as follows:

  1. Ammonia solution 10% or ethyl alcohol. It is worth softening the stain, and after a couple of minutes, clean it with the corner of a spatula.
  2. Freeze - Place the bag in the freezer for two hours, then scrape off the resin.
  3. Heating.

    Apply white paper to the epoxy stain, iron with an iron until the composition melts. You can remove it with any suitable tool.

There is another, more exotic way to remove stains. So, the resin can dissolve from the effects of soda (Coca-Cola or Pepsi), and then it can be removed from the fabric. You can also lubricate drips by means of the drugstore drug "Dimexide".

It should be mixed with water in a ratio of 1 to 3, moisten the item and remove the stain. After using any method, you should wash the product in a machine with the simplest washing powder.

Glass and tile cleaning

You know how to dissolve epoxy at home. If, after finishing work in the bathroom, there are ugly influxes on the surface of the walls or on the floor, it will not be difficult to remove them. Fresh stains should be removed by simply wiping with a damp cloth and soap and water solution.

Dried defects should be removed by heating, freezing with refrigerant, and also with chemical solvents. The tile is almost not subject to damage from such methods of exposure, and therefore it is possible to get rid of the problem at any time.
